Abstract

1518476 Leak detection WESTINGHOUSE ELECTRIC CORP 5 April 1977 [5 April 1976] 14321/77 Heading G1S In a nuclear reactor having a liquid metal-towater tube type heat exchanger 12 leaks are detected by adding helium to the water and analysing the liquid metal to determine any increase in its helium content. As shown the helium is added at 36 and the liquid metal, typically sodium or sodium-potassium combination, is sampled at 28 and passed to flash tank 30 where any helium is separated from the liquid metal. The helium is then passed to a helium diffuser 32 which concentrates the gas before passing it to a helium detector 34 such as a mass spectrograph or a gas chromatograph. In an alternative embodiment, Fig. 6 (not shown), the helium is concentrated by a molecular sieve (58) positioned between two orifices (56), (60). Instead of monitoring the helium in the liquid metal directly, the cover gas 26 in the reactor 10 can be sampled for helium.
